Smith & Wesson M&P AR15 pistol borescoped!

7.5" barrel with less than 150 rounds (so I'm told) and lightly cleaned. Based on typical wear points on the BCG, it does seem like it's been shot very little.

You realize you can adjust the mirror so it straight then lock it with the focus ring...

I don't know what you mean by straight (it's always straight), but yes, that's how you focus it.
